EDIVARD 0. SMITH, OF SYRACUSE, NEW YORIC BLIND-STOP.

SPECIFICATION forming part of Letters Patent No. 364,054, dated May 31, 1887.

Application filed March 14, 1887. Serial No. 230,834. (No model.)

To all whom it may concern:

Be it known that I, EDWARD 0. SMITH, of Syracuse, in the county of Onondaga, in the State of New York,'have invented new and useful Improvements in Blind-Slat Adjusters, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to devices employed for holding, either in a closed or an open position or at different angles of inclination, the pivoted slats of window-blinds, so as to prevent said slats from rattling and from being turned by wind blowing against the same.

The invention consists in the improved construction and combination of parts, as hereinafter fully described, and specifically set forth in the claims.

In the annexed drawings, Figure 1 is a face view ofthat portion of a window-blind to which my invention is applied. Fig. 2 is aside view of my improved blind-slat adjuster. Figs. 3 and 4 are detached perspective views of those parts of the slat-adjuster which are attached directlyto the blind-rod. Fig. 5 is a detached front View of the part which is hinged on the blind, and Fig. 6 is a side view of the device by which I connect the upper and lower blindrods soas to operate the same in unison.

Similar letters of reference indicate corresponding parts.

A represents the bottom rail of a windowblind. B B are the pivoted slats; and R denotes the blind-rod, which is connected with one edge of each blind-slat in the usual manner, to op.- erate the slats in unison. To the bottom rail, A, is rigidly secured a plate, F, on which is hinged or pivoted a vertically-oscillatory arm, 0, the oscillatory end of which is bifurcated. To the lower end of the blind-rod R are secured two spring-plates, D D, preferably formed of sheet metal and with concavo-convex attaching-shanksz't' at their upper ends, which shanks embrace the end portion of the rod R, and are provided with spurs or clinching-prongs Z Z, which are adapted to pierce the rod, and thus grasp the same, so as to firmly hold said attaching-shanks on the rod. Below the end of the rod the plates D D are formed with offsets a a, whereby they cross each other, and with downward extensions 1) b, and return-offsets c 0, terminating with down ward-proj ecti ng ends d (Z, which latter are provided with eyes f f. The portions a a of the aforesaid plates are provided with-slots e e at their point of crossing, each of said slots extending through half of the width of the plate, so as to allow one plate to V jacent side of the bifurcated end of the arm 0 projects a lug, h, which is adapted to enter one of the aforesaid perforations at a time, and thus lock the plates D D at different angles on the arm 0.

The plates D D are formed of spring metal, and normally stand with their end portions, d d, 'apart from each other and closely againstthe' inner sides of the bifurcated end of the arm 0.

The adjustment of the slats B B is effected by pressing against the exterior of the portions 2) b of the plates D D, soas to compress said plates, and thus throw the perforated end portion, (I, out of engagement with the lug h. The arm 0 is thus liberated to swing on its pivot on the plate F, and the arms D D can move freely on their pivots on the arm 0. This allows the rod R to be moved up or down, to set the slats b b either into closed or open positions or into any desired angle of inclination. By releasing the plates D D from the aforesaid compression they are allowed to spring apart. The lug h, then entering one of the perforations 0, looks the aforesaid parts in their desired position.

In order to permit of adjusting simultaneously the slats of the upper and lower panels of the blind, I connect the two blind-rods BR, by a metallic strap, 1, which has its ends provided with clinching-prongs n 12, adapted to grasp the ends of the aforesaid rods, as represented in Fig. 6 of the drawings.

Having described my invention,what I claim as new, and desire to secure by Letters Patent, 1s-

1. A. blindslat adjuster comprising springplates projecting from the end of the blind-rod,

an arm hinged at one end on the blind and at the opposite end to the aforesaid spring'plates, and catches adapted to retain said parts at 5 different angles to each other, as set forth.

2. The combination, with a windowblind, of a verticallyoscillatory arm hinged thereon directly under the lower end of the blind-rod and bifurcated at its oscillatory end, springplates projecting from the lower end of the blind-rod and having their lower ends pivoted to the inner sides of the bifurcated end of the arm, perforations in the pivoted end of one of the spring-plates, and a lug projecting from the adjacent side of the arm and adapted to enter one of the perforations, substantially as described and shown. 1

3. In combination with the blind-rod and the arm pivoted on the blind directly below said 20 rod, the spring-plates D D, secured at one end to opposite sides of the blind-rod and formed with offsets a a, whereby they cross each other, downward extensions 1) b, return-ofi'sets c c, and downward-projecting ends d d, and provided with the slots 0 e at their point of cross- 25 ing and with the eyesffin their end portions, and perforations 0 o 0, arranged around one of said eyes, the pi'ntle 9, connecting the springplates to the pivoted arm, and the lug h, projecting from said arm, substantially as de- 0 scribed and shown.

In testimony whereof I have hereunto signed my name and affixed my seal, in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York, 3 5 this 5th day of March, 1887.
